The DBH 8391 is a radial shaft lip seal that retains lubricant and blocks contaminants from reaching rotating shafts. It fits a 19 mm shaft, a 27 mm housing bore and a 5.00 mm axial height, and its Lt lip design suits moderate-speed rotation. MR Industrial Accessories supplies this brand and helps you match the seal to your equipment.

This seal carries the code 8391 and the Lt lip configuration. Its three key measurements are: shaft 19 mm, housing bore 27 mm, and height 5.00 mm. Inside, an elastomeric lip works with a metal case that holds the seal firmly in the housing. The result is a barrier that keeps oil or grease where it belongs and keeps dust, water and particles out, which helps bearings and bushings last longer.

You will find seals in this size range on small gearboxes, pumps, electric motors, reducers and other power transmission units. They also appear on conveyors, agricultural equipment and hydraulic systems where a compact seal must still do a reliable job. Because it is a wear part, replace it when you see leaks, or when the lip feels hard, cracked or cut. The shaft itself should have the right hardness and surface finish for dynamic sealing.

During installation, make sure the housing and shaft are clean and free of burrs. Coat the lip with the same lubricant used in the assembly, then press the seal in evenly on its outer ring. Never drive it in by the lip. When choosing a replacement, consider rotation speed, operating temperature and the fluid being retained. If the shaft is worn, a version with an auxiliary lip may be worth reviewing.

To order, the designation 8391 and the dimensions 19 x 27 x 5 mm are the data you need. If you want an equivalent, send that code or those measurements by WhatsApp and the team can point you to options in the same seal category while keeping the housing and shaft sizes correct. They can also help identify the seal from the brand and model of the machine where it is mounted.
